Title: Absorption dynamometer torque-measuring device and calibration method
Inventor: BRASSERT WALTER L
IPC: G01L25/00
Filed: 1994-07-13
Abstract: An in-line torque meter for use with an absorption dynamometer (10) in which the twist of a rotating shaft (70) is measured by a single sensor (64) on the adjacent stationary structure. Attached to and rotating with the shaft are two sleeves (66, 68) with interleaved projecting teeth (67, 69). When the shaft is twisted by the applied torque, the teeth on the two sleeves are angularly displaced with respect to each other. This angular displacement is measured as a phase shift in the signal generated by the sensor. The torque sensor is moveable past the teeth when the torque shaft is stationary. The movement of the torque sensor generates a signal representative of the torque or twist in the torque shaft, thereby allowing a zero speed calibration check. <IMAGE>

Title: Improvements Relating to Nuclear Reactors
Inventor: HALL GEORGE
IPC: G21C19/303
Filed: 1996-01-12
Abstract: A problem exists with gas cooled nuclear reactors, such as MAGNOX and AGR reactors, in that reactions occurring in the coolant under irradiation lead to the formation of deposits, eg, of carbon within the primary coolant circuit. Carbon deposits on the boiler and reheater tubes has a detrimental effect on the efficiency of the plant. Accordingly the invention provides a method for at least partially removing deposits from a reactor-side surface(s) of at least one heat exchange apparatus of a gas cooled thermal nuclear reactor comprising injecting a gas in a localised manner into a pressure vessel of the reactor such that a portion of the gas is directed to and reacts with deposits on said surface(s) of said heat exchange apparatus, any remainder of said gas being substantially consumed within said heat exchange apparatus by coolant gas. Advantageously the method may be performed during normal reactor operation. The gas may be predominantly O 2 .

Patent GB-2314926-A (GB)
Title: Electron detector
Inventor: COWHAM MICHAEL JOHN
IPC: H01J37/244
Filed: 1996-07-01
Abstract: In a Scanning Electron Microscope (SEM) a spot made from a very narrow beam of electrons (11) is scanned in fine strips across the specimen (18), and an image is built up from the electrons back-scattered from an area of the specimen being scanned. To gather these back-scattered electrons it is presently common to employ a scintillator layer on the front face of a light guide that directs the generated light to a photomultiplier tube (23). However, having the scintillator layer on the front face means that the light has to pass through the layer to enter the guide, which necessarily wastes light by absorption within the thickness of layer material; the invention proposes instead that the light guide (22) have on its back side a scintillator layer (34) angled as though to reflect received electrons along the guide to the PMT (23). In this way the PMT is actually "looking at", and so receiving light directly from, the front, or input side, of the scintillator layer, and thus the light emitted by the layer does not need to travel through the layer to get to the PMT, and is therefore not attenuated by that layer - and a detector system of the invention is therefore several, even tens, of times more sensitive that one of the Art.

Title: Radiotelephone proximity detector
Inventor: BRIFFETT NEIL
IPC: H04M1/724
Filed: 1996-10-23
Abstract: A radiotelephone proximity detector comprises of a telephone proximity unit 16 associated with a mobile telephone and a belt clip proximity unit 46 associated with a user, both containing transceivers 74, 54 respectively. Transmitter 76 produces a master signal S2 to be received and demodulated by a receiver 58 which communicates the strength of the signal to a controller 52. If the receiver does not receive a signal within a predetermined time interval or the magnitude of the signal received is less than a given value, an alarm is actuated indicating that the two units are separated by more than an acceptable distance, and normal operation of the telephone becomes inhibited. If an appropriate signal is received, the slave unit responds by sending a response signal S1 which is received and analysed in similar fashion by receiver 78. Both units can be coupled via contacts 62, 82 which places the units in a standby mode.

Title: Transponder device with overvoltage protection
Inventor: ARISAWA SHIGERU
IPC: G07B15/02
Filed: 1996-11-19
Abstract: A transponder-based ticket 23, for automatic travel ticket 'clipping', includes control circuitry for preventing damage to its components when placed too near to a transmitting, interrogating/writing device (2, fig.5). Included in the control circuitry is a variable capacitor C23, which is fed a rectified version of the voltage appearing on loop antenna 10 via resistor R23. Capacitor C23 is normally set so that the resonant circuit is tuned to the transmitting frequency of the interrogator. However, if the voltage received is too large, the capacitance of C23 is adjusted, via the feedback signal from R23, so that the resonant circuit oscillates at a frequency offset from the interrogator's transmitting frequency, thus reducing the amplitude of the received signal. When transmitting data from the transponder, FET 24 switches resistance R24 in and out of the resonant circuit, thereby enabling two different resonant frequencies to be used for transmission.
